I'm a total amateur so please don't judge my lack of knowledge. I'm a film major with a lot of interest in science. So I know that it is not possible to travel faster that the speed of light. But I had this idea the other day: If a capsule traveling at 99.9% of the speed of light and there is another object within this capsule, then it can still move forward right? And when it does, it is technically moving faster than the speed of light, right?
